Overall, they have a set of 20 teeth, like all guinea pigs. [5] The teeth are hypsodont like all species of guinea pigs and converge towards the front. [4] The ...

The greatest number of teeth in any known placental land mammal [specify] was 48, with a formula of 3.1.5.3 3.1.5.3. [9] However, no living placental mammal has this number. In extant placental mammals, the maximum dental formula is 3.1.4.3 3.1.4.3 for pigs. Mammalian tooth counts are usually identical in the upper and lower jaws, but not always.
The teeth have enamel on the outside, which is often orange-yellow due to the incorporation of iron-containing pigments, [6] and exposed dentin on the inside, so they self-sharpen during gnawing. On the other hand, continually growing molars are found in some rodent species, such as the sibling vole and the guinea pig.
The common yellow-toothed cavy (Galea musteloides) is a species of rodent in the family Caviidae, closely related to the domesticated guinea pig. [2] It is found in Argentina, Bolivia, Chile, and Peru. Its karyotype has 2n = 68 and FN = 136. [2]
